[[p. 23]] "Allow me to call the attention of the Entomological Society to what seems to me a
novel and most erroneous as well as inconvenient interpretation of the law of priority: it is, that
of transferring a name long borne by one insect (but which it has lost by being found to be but a
sex or variety) to another insect which has been erroneously referred to the same species. This
has been done by the late Mr. Doubleday, who has changed Ornithoptera Remus, a name which
for fifty years has been invariably borne by one well-known species, into O. Panthous, a name
which for a still longer period has been applied to the female of O. Priamus. Such a change
would be most inadvisable, even were the principle on which it was made a good one; whereas it
is one which gives, as it were, a premium to error. Linnæus described the female of Priamus as a
distinct species (Panthous) and Remus as the male of Panthous. Cramer corrected the latter error
and figured the two sexes of Remus correctly, giving the species for the first time a distinct
name. This name it appears to me cannot be changed for that of Linnæus, who erroneously
supposed the species to be the same as one he had previously named, although that name has
been reduced to a synonym. The two errors of Linnæus should not be allowed to take precedence
of Cramer, who first correctly named the species. The question here raised is of importance
because an analogous case is now open for decision. P. Darsius of G. R. Gray was previously
figured by Doubleday as the male of Amphimedon. Now, Amphimedon is certainly the female of
Helena, and, if the rule holds good, the new species Darsius must take the old name of
Amphimedon, just as Remus has been made by Messrs. E. Doubleday and G. R. Gray, to take the
name of Panthous. Such a practice will certainly not be generally followed, and I would humbly
suggest that it is one of the duties of an Entomological [[p. 24]] Society, to check, by an
expression of their opinion, all that tends still further to confuse the nomenclature and synonymy.
